Greece but with additional (impossible?) requests

We are searching for a villa with pool or if it is beach side the pool isn't needed- Sleeping 6 and near restaurants.The children are teenagers and would like to sail or windsurf . We'd also like to be able to hire a small motor boat to get around and visit beaches.It could be our last big family holiday so want to make it special.

It doesn't have to be Greece if these options are available elsewhere.

Have searched the usual villa rental sites but haven't yet found anything.
